Have a look at the video interview with Andy Horn that was done for a talk he had given at the 2014 Cape Construction Expo entitled “BEYOND SUSTAINABILILITY – Regenerative Design and the Transition Towards a Post Carbon Architecture”

Solving pressing issues locally

We have recently completed a revitalization project for a heritage site in Mamre near Cape Town. They not only used local materials, but also involved and empowered the community by providing public participation forums and running a series of training programmes.
By building in this sustainable way, Eco Design Architects managed to address two of the most pressing issues of South Africa: unemployment and environmental pollution.
